From idea to app in three steps

No crazy shi. Just describe what you want and watch it happen.

Describe your app
Plain English. No technical knowledge required — just the idea. appslapper figures out the rest.
02
AI writes the code
A complete, working app — React frontend, Express backend, SQLite database. Real code in a real Docker container. Not a mockup.
03
Iterate in chat
See it live in the preview pane. Ask for changes. appslapper updates the code and refreshes in seconds.
